Title: Improvements in and relating to the production of reduced particle size from spray-solidified powder-like or granular materials
IPC: C11D13/20
Filed: 1933-03-04
Abstract: <PICT:0417449/III/1> The grain size of pulverulent or granular materials e.g. soap powders obtained by pulverisation of molten substances or mixtures of substances, which are solid at room temperatures, is reduced by spraying the molten material to produce a subdivided form and further subdividing the products obtained by conveying them pneumatically through a tubular conduit so that they are subjected to frictional action against the walls of the conduit. Molten soap sprayed through a jet B into a chamber C is coagulated by air sucked in by an exhauster A.  The air and entrained particles pass through a tube system D in which the particles are reduced by friction to the required size.  The particles are separated from the air in a cyclone E and collected in a vessel H.  In a modification the material is sprayed upwardly and the particles entrained in a downward current of air which may be cooled by extra air drawn in through vents, the air and particles being finally drawn through a tube system by the exhauster producing the air current. Specifications 269,506, 269,516, and 291,041, [all in Class 91], are referred to.

In another arrangement, coil 24 is in series with blade 20, the pull in position 21 being insufficient to move the blade, but sufficient in position 22 to hold it. Another modification provides a separate relay to " flash " the main and real lamps simultaneously.

Abstract: 181,089. Pierpont, F. H., and Lanston Monotype Corporation, Ltd. March 3, 1921. Moulds, low quad. In a single-type casting and composing machine of the kind described in Specification 8633/99, provided with a mould for casting low quads, the cut-off blade of which is actuated by mechanism such as that described in Specification 22303/13, means are provided to ensure that the force acting on the main mould blade, to dimension the mould is the same whether a low quad or a full-height type body is being cast. The lever P which actuates the cut-off blade H<1> is pivoted at p on a lever Q, pivoted at q to the mould A or to a bracket attached thereto, the lever P being provided with an opening p<1> through which the pivot pin passes. When a full-height type body is to be cast, an actuator 0 turns the lever P on its pivot until the edge of the opening p<1> engages the pin q, after which both levers turn together on the pivot q, so that the lever P withdraws the cut-off blade H<1> against a shoulder on the main mould blade H. When a low quad is to be cast, the actuator 0<1> moves the lever P, which first turns on the end engaging the blade and so causes the lever Q to turn on its pivot and force its forward end against the end of the rod G, which operates the main blade H. In each case, the force acting on the rod G to withdraw the main blade is increased by the force acting on the lever P. Specifications 18231/06 and 16789/10 also are referred to.

Title: Enzymatic production of wort concentrates for kvass and other beers
Inventor: KOROLEV DMITRY AMOSOVICH
IPC: C12C7/047
Filed: 1966-02-18
Abstract: In a method of producing a concentrated wort, the hemicellulose intercellular walls in a mixture of freshly germinated rye or barley malt and rye or barley flour are hydrolyzed by cytolytic enzymes. The flour and malt starches in the mash thus produced are subjected to proteolysis and saccharification, the solid matter is separated off to give a wort, and the wort is concentrated at an elevated temperature with the formation of melanoidins.  The hydrolysis of the hemicellulose may be effected by the cytolytic enzymes present in the freshly germinated malt or by 0.1-0.4% of the dry weight of the flour and malt mixture of a culture of trichothecium roseum or extract thereof.  A mixture of 50-80% rye flour and 50-20% of freshly germinated rye malt is blended with water in a ratio of between 1:3 and 1:4, the cytolytic hydrolysis is effected at a temperature of 40-42 DEG C. for a period of one to two hours, and this is followed by proteolysis at 50-52 DEG C. for one to two hours, saccharification for 30 minutes at 63-65 DEG C. and a further heating at 72-75 DEG C. to complete the saccharification, whereby the wort thus obtained has a concentration of 14-18 Balling.  The wort is then concentrated in vacuo at 53-64 DEG C. to 63-68 Balling and is then heated to a temperature of 80-120 DEG C. with the formation of melanoidins. The concentrated wort may be blended with other ingredients used in the making of kvass such as sugar syrup, citric or lactic acid, and spices or flavouring agents.  A kvass drink is produced by diluting the concentrate with aerated water.  The rye malt is preferably produced under specified conditions of steeping and germination.  The rye flour should be boiled in water under pressure and cooled before being added to the malt.
